hi pd-list!
i have recently tried to build some filters using cpole and czero, not
completely unsuccessfull (at least the lowpass sounds somewhat like a
lowpass...), but i have a problem calculating the right gain (or
attenuation) factor. for the lp it seems to work more or less (ok
for a subtractive synth, but still not good enough for effects etc.),
but the hp is either too lound for lower frequencies and low resonance,
or hardly audible.
i think there might be a better way to find out the right gain
than 'try and error'.
and its getting worse with more poles involved...
so is it possible to get the gain from the poles and zeros, without
calculating all coefficients?
bis denn!
martin
